What Chlorsig is used for

Chlorsig contains chloramphenicol, a synthetic antibiotic, as the active ingredient.

Chlorsig is available as eye drops and eye ointment, for external use only.

It is used to treat an eye infection called bacterial conjunctivitis, which is a bacterial infection involving the mucous membrane of the surface of the eye.

The most common symptom is the presence of a sticky yellow-white discharge with mucus and pus (or glued eyes, especially in the morning on waking). Other symptoms include a gritty sensation in the eye, redness, irritation and watering of the eyes. The infection usually starts in one eye and then spreads to the other.

Ask your doctor, pharmacist or optometrist if you have any questions about why Chlorsig has been prescribed for you.

They may have prescribed it for another purpose.

When you must not use it

Do not use Chlorsig if you are allergic to chloramphenicol or any of the ingredients listed at the end of this leaflet.

Some of the symptoms of an allergic reaction to Chlorsig may include irritation, pain and swelling in the eye. Skin rashes, blisters and fever may also occur.

Do not give Chlorsig to children under 2 years of age unless your doctor or optometrist tells you.

Do not use Chlorsig after the expiry date (EXP.) printed on the pack.

Do not use Chlorsig if the packaging is torn, broken or shows signs of tampering.

apply one drop into the pouch

close the eyes (do not rub them) and try not to blink for a short time

apply gentle pressure for a few minutes with a finger to the bridge of the nose to prevent the medicine being drained from the eye

blot excess solution around the eye with a tissue

if instilling more than one drop in an eye, separate each installation by several minutes to avoid washing drops out of the eye

If you are unsure about whether to use your next dose, speak to your doctor, optometrist or pharmacist

Do not try to make up for missed doses by using more than one dose at a time.

This may increase the chance of you getting an unwanted side effect.

If you use too much (overdose):

Accidental ingestion of the drug in adults is unlikely to cause any toxicity due to the low content of antibiotic, but consult your doctor or Poison Information Centre (see below).
